[PATCH V8 0/8] Cleancache

This is a courtesy repost to lkml and linux-mm.  As of 2.6.39-rc1,
Linus has said that he will review cleancache but hasn't yet, so
I am updating the patchset to the very latest bits.  The patchset
can be pulled from:

git://git.kernel.org/pub/scm/linux/kernel/git/djm/tmem.git
	(branch stable/cleancache-v8-with-tmem)

Version 8 of the cleancache patchset:
- Rebase to 2.6.39-rc3
- Resolve trivial merge conflicts for linux-next 
- Adapt to recent remove_from_page_cache patchset by Minchan Kim
- Fix exportfs issue that affected btrfs under certain circumstances
- Change two macros to static inlines (per akpm)
- Minor documentation changes

Following your request to Dan, I just wanted to let you know that
we've been carrying a variant of this code since 2.6.31 in our
consumer and enterprise product (Xen) kernels. It would therefore
simplify our kernel maintenance if this got merged in the
foreseeable future.
